GPA — Grade Point Average — is a single number that summarizes your academic performance. Colleges use it for admissions, employers often ask for it, and scholarships frequently require a minimum. Here is exactly how it is calculated.
The 4.0 Scale
Most US schools use the 4.0 scale, where each letter grade corresponds to a grade point value:
| Letter Grade | Percentage | Grade Points (Unweighted) |
|---|---|---|
| A+ / A | 90–100% | 4.0 |
| A− | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B− | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C− | 70–72% | 1.7 |
| D | 60–69% | 1.0 |
| F | Below 60% | 0.0 |
Step-by-Step Calculation
GPA is a weighted average of your grade points, where the weight is the number of credit hours for each course.
The formula: GPA = Sum of (Grade Points × Credit Hours) ÷ Total Credit Hours
Example with 4 courses:
| Course | Grade | Credits | Grade Points × Credits |
|---|---|---|---|
| English | A (4.0) | 3 | 12.0 |
| Math | B+ (3.3) | 4 | 13.2 |
| History | A− (3.7) | 3 | 11.1 |
| Biology | C+ (2.3) | 3 | 6.9 |
| Total | 13 | 43.2 |
GPA = 43.2 ÷ 13 = 3.32
Weighted vs. Unweighted GPA
The example above is an unweighted GPA — every course counts equally regardless of difficulty. A weighted GPA gives extra points for honors, AP, or IB courses. The typical bonus is 0.5 for honors and 1.0 for AP/IB. So an A in an AP class counts as 5.0 on a weighted scale.
Colleges often recalculate your GPA using their own method anyway, so both numbers matter. Admissions officers will look at the course rigor alongside the GPA.
High school note: Some schools do not include physical education or electives in GPA calculation. Check your school's policy for which courses count.
What GPA Do You Need?
| GPA | Honor Level | General Benchmark |
|---|---|---|
| 3.9–4.0 | Summa Cum Laude | Highly selective universities |
| 3.7–3.89 | Magna Cum Laude | Competitive universities, merit scholarships |
| 3.5–3.69 | Cum Laude | Most 4-year colleges |
| 3.0–3.49 | Good Standing | Average college applicant |
| 2.0–2.99 | Passing | Minimum for most programs |
| Below 2.0 | Academic Probation Risk | May affect enrollment |
How to Raise a Low GPA
- Take more credits. GPA changes slowly because past grades are locked in. More credits = more opportunities to pull up the average.
- Retake failed or low-grade courses. Many schools replace the original grade or average both — check your school's policy.
- Focus on high-credit courses. A 4-credit course moves your GPA more than a 1-credit course. Prioritize performance in courses with more credits.
- Talk to your academic advisor. They may know about grade forgiveness, course withdrawal options, or academic renewal programs.
